“Jimmy’s a heckuva football coach. I’m very proud of what he’s accomplished. He always brings a blue collar approach and I think you see that with his team,” Packers Coach Mike McCarthy said of first-year 49ers head coach Jim Tomsula. The coaches are from neighboring communities in Pittsburgh.

“I remember when he was coming up. He was a good player. He’s worked his way up through the system,” McCarthy said of Tomsula. “There’s a big presence from Western Pa. in the NFL. We all take pride in that.”

McCarthy will be armed with the best quarterback in the league, Aaron Rodgers, who’s currently playing the best football of his career. Tomsula’s quarterback is Colin Kaepernick, who’s struggled early this season but is 3-0 vs. the Packers, including two playoff wins.

“He’s a dynamic player. We’ve had issues with him in the past. He’s a different type of quarterback to prepare for,” McCarthy said of Kaepernick, a read-option quarterback known more for his running than his passing.

McCarthy was asked if Rodgers might run the read-option.

“He makes too much money to run the option,” McCarthy said. “Aaron Rodgers is really in the groove. Really, our football team, coming out of the offseason program, we felt really good. They’ve really been in sync.”

Davante Adams wasn’t expected to practice on Wednesday; he reinjured his ankle on Monday night. Jeff Janis takes on a greater presence in Adams’ absence.

“Jeff Janis is doing a heckuva job. He’s definitely making the leap. He’s definitely a part of the flow of our offense,” McCarthy said.
